Will too little sleep lead to high blood pressure?

Sleep and BP. There is some data that suggest that sleep deprivation can raise blood pressure. When we don't sleep enough, our bodies tend to have overactive fight or flight activity. This can theoretically raise blood pressure. Some sleep disorders like obstructive sleep apnea is shown to affect blood pressure not only by stopping breathing but by the fragmentation of sleep.
Sleepless. Too little sleep will not necessarily lead to high blood pressure unless the too little sleep is related to sleep apnea or some other physiologic state associated with increased bp.
